I don't think i've seen anybody recommend Aggron for Uruto's second Capture.
>No type overlap
>Big and Menacing with tons of raw strength, which is definitely up the green goblin's alley.
>It's mega form, unlike Sableye's being more balanced between Physical and Special defense is focused entirely on the Physical side of things. This let's it act as a more refined wall in case Uruto would want to switch things up and let his main partner go full prankster mode.
>Speaking of everyone's favorite gem consumer, Aggron is part rock type. The jokes write themselves.
>Many of it's dex entries states how it likes to live in forests and mountains claiming those areas as it's domains. Urotu obviously prefers the outdoors evidence by the fact that he declined the room that was made for him in the ship.
>But most importantly above all else. Heavy Slam and Gyro Ball. Picture a scenario where the Rising Volttacklers need to break into one of Spinels buildings but they just don't have enough strength or manpower to do so. THEN INCOMES UROTU WITH THE STEAL CHAI- I MEAN MEGA AGGRON WITH HEAVY SLAM/GYRO BALL !
Of course with all that being said i still prefer a Golisopod on his team.
